As has been the case for a long time, Dortmund don't care about their rivalry with Bayern in fact very many of their stars have moved to Bayern and some even come back when they are old there is no rivalry between them I think, Bayern with their own targets and Dortmund with their mission to be able to make money from the players they sell when they shine, these two teams I think have different visions, and fortunately the Dortmund fnas always support their team no matter what.
Yes that's a unique fact, Dortmund fans still support their club with all their hearts even though the club's vision and mission is not to win and win trophies. If they didn't sell their star players maybe they would get bigger profits by winning various championship trophies, the Bundes League and Champions League would give them a lot of bonuses. I think Dortmund will change the direction of the club's policy if it changes ownership and is acquired by a new owner.
As far as I can see their best achievement in the Bundesliga in the last decade is winning twice in a row in the 2010-2012 period. After that until last season Bayern Munchen dominance was difficult for them to break. Munchen won it for the full decade in 2012-2023, which is extraordinary and deserves appreciation.
